A letter of authorization is your HMO's approval for a consultation, test or admission. The hospital needs it before the HMO can be billed.

How do I request one?

Send an LOA request on this site, or ask admitting. We contact your HMO and call you back with the answer.

What if my HMO does not approve?

We will tell you what was not approved and why, so you can decide with your doctor whether to proceed as a paying patient.
